It's cold and the lakes are freezing around here. I'm missing being out on the water and checking out the aquatic plants on this #MacrophyteMonday. Anyone have any nice aquatic plant photos to share to green up my feed?

This team has been working on lakes all over the Huron-Manistee National Forests this summer, from tiny lakes to big ones like Hamlin and Mitchell. These baseline surveys will inform future conservation decisions. Go team! #MacrophyteMonday

Field season isn't over yet! I finally joined our summer macrophyte survey crew in the field last week for a beautiful day assessing the plants in Upper Hamlin Lake, Mason County, MI. After spending the summer working together, this MSU student team is a well-oiled machine! #MacrophyteMonday

The tiny flower of an aquatic plant. It is yellow and looks like a tiny orchid on a very thin stem held above the damp plant.

Happy #MacrophyteMonday! I photographed this flower of an aquatic plant along the shore of a lake in the Upper Peninsula of Michigan today. Can you name it? Bonus points for naming the floating-leaf plant in the background...

Its winter form looks different too - narrow, flattened blue-green leaves with fewer stems and thinner roots - a true seasonal survivor with a head-start on spring! 🌱

You know that invasive plants are bad for our lakes. But do you know how to identify them? Do you know there's a Michigan program where you can learn to identify them, how to find them, and how to report them? It's the Exotic Aquatic Plant Watch! #MacrophyteMonday

🌿 INVASIVE #MacrophyteMonday: This pond is completely smothered by #waterhyacinth - so dense you can’t even tell where the land ends & #water begins, making it a safety hazard for pedestrians, children, & pets.

🚫 It blocks flow, chokes oxygen levels, alters water chemistry, & destroys habitat. 🧵
